Animal Deterrent Using High Voltage Spark Generator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deterring animals from entering protected areas, such as electronic fences and motion sensor-light or sound generators, are expensive, hazardous, and ineffective against determined animals like bears and large dogs.
Innovation Solution
A device comprising a high voltage spark generator powered by a sensor that detects motion or sound, producing a loud and bright spark simulating lightning, which is feared by most animals, along with optional features like a pulse timer and solar charging for autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion sensor and light or sound generator are used to detect and deter animals, then the device can detect animal presence, but the deterrence effectiveness is very limited against determined animals
Solution Approach 1:
The patent changes the parameter of deterrent output from conventional light/sound to high voltage electrical discharge. This parameter change creates a more intense and frightening effect that reliably deters even determined animals like bears and coyotes, while the automated trigger system keeps the device simple to operate.
Solution Approach 2:
The patent replaces the mechanical/electronic components of conventional deterrents (motors for moving parts, complex control systems) with a high voltage spark generator that produces a simple, intense electrical discharge. This substitution achieves reliable deterrence without requiring complex mechanical mechanisms.
2Reliability
If electronic fences are used to protect areas, then the protected area is secured, but the installation and maintenance costs are expensive and they create hazards for children and pets
Solution Approach 1:
The patent applies partial action by using a high voltage spark generator that delivers a brief, intense electrical discharge only when animals approach, rather than continuous protection. This provides effective area protection while avoiding continuous exposure that would create hazards for children and pets.
Solution Approach 2:
The patent applies local quality by concentrating the deterrent effect at the boundary where animals approach (using motion-activated sensors), rather than creating a continuous hazardous field throughout the protected area. This ensures protection at critical points while maintaining safety in other areas.
3Reliability
If conventional light and sound deterrents are used, then the device can alert animals, but determined animals like bears and large dogs are not easily discouraged
Solution Approach 1:
The patent changes the deterrent parameter from conventional light/sound to high voltage electrical discharge, which creates a more intense and frightening effect that reliably deters even determined animals. The automated sensor trigger ensures this high-energy output is activated only when needed, optimizing power consumption.
Solution Approach 2:
The patent uses periodic action by activating the high voltage spark generator only in response to detected motion or sound, rather than continuous operation. This provides reliable deterrence when animals approach while minimizing overall power consumption during idle periods.

Data Source
AI summary
An animal deterrent is provided. The animal deterrent includes a housing having a high voltage spark generator disposed within. A power source, such as a battery, is connected to the high voltage spark generator. A sensor may be connected to the battery and is operable to detect at least one of a motion and a sound. When the sensor detects at least one of the motion and the sound, the power source powers the high voltage spark generator so that the high voltage spark generator generates high voltage sparks. The high voltage sparks produce a sound and a light, along with ozone scaring animals away.
